Answer 1

Answer: (a) 3

In humans there are normally 12 pairs of ribs. The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8^th , 9^th and 10^th pairs are called as false ribs which do not join the sternum directly but are connected to the 7^th rib by cartilage. The 11^th and 12^th pairs are called floating ribs. So, there are 3 pairs of false ribs present. So, the correct answer is '3'.
